cg to unitycg : Glowing shader

Hi, I find a shader on Ogre that do exactly what I want but I never do Cg/HLSL before. I understand how to exploit Cg/HLSL but this shader is really complicated according to me :x http://www.ogre3d.org/tikiwiki/Glow&structure=Cookbook If someone can help me to convert it to Unity or just integrate it It just could be really really great. Thanks to all for your next help.
